Psychomotor Vigilance Test (PVT)
The Psychomotor Vigilance Test (PVT) is a widely used cognitive test designed to assess sustained attention and reaction time. It is the de-facto gold standard for objectively assessing behavioral alertness and very sensitive to sleep loss and circadian misalignment. Furthermore, due to its simplicity, the PVT is not affected by aptitude or practice effects like the majority of other, more complex cognitive tests.
How it works?
The PVT measures response times to stimuli that are presented at random inter-stimulus intervals. The precise measurement of these response times is of critical importance for the validity of the PVT. The test records reaction times, lapses, false starts, etc.
Key Advantages
- Sensitivity to Subtle Changes:
The PVT can detect even small impairments in attention and alertness.
- Minimal Practice Effects:
Repeated testing with the PVT does not significantly affect performance, allowing for reliable longitudinal assessments.
- Ease of Administration:
The PVT is a simple and straightforward test that can be administered in various settings.
Applications of PVT
- Sleep Research
- Occupational Settings
- Medication Research
- Aging Research
- Sports and Exercise Science
Web-based PVT by NeuroUX
NeuroUX offers a web-based version of PVT which can be administered on a smartphone web browser, enabling participants to perform the test on their devices without the need for app installation. The test can be accessed through a simple text message link.
Available Versions:
- PVT (Standard Version):
This version replicates the traditional PVT with a 10-minute testing duration. It offers comprehensive data on sustained attention and reaction times, making it ideal for in-depth studies.
- PVT-B (Brief Version):
Our PVT-B condenses the traditional format into a quick 3-minute assessment. While more compact, it retains the core features necessary for meaningful insights, offering a balance of efficiency and precision.
- PVT-BA (Adaptive Version):
PVT-BA (Adaptive Version) builds on the 3-minute PVT-B and uses a dynamic strategy. Instead of a fixed duration, it collects response time data until a statistical threshold is met, then ends the test once vigilance can be confidently assessed.
All versions are accessible via our web-based platform, ensuring seamless integration into remote or in-lab studies.
Here is how the formats compare:
Why Choose NeuroUX's PVT?
NeuroUX’s platform ensures researchers have the tools they need to conduct precise, reliable, and scalable studies:
- Web-Based Platform: Cross-platform accessibility without the need for participants to download apps.
- Accessibility Through Text Messages: Links sent via SMS with options for follow-up reminders.
- Scalable for Large Studies: Convenient for large-scale studies with participants using personal devices.
- Different Versions: Standard and brief formats to meet diverse research needs.
- Integrated Tools: Seamless integration with NeuroUX’s suite of validated cognitive tests, EMA, and wearables.
- User-Friendly Experience: Designed for simplicity, ensuring participants can easily complete the test without additional guidance.
Recommendations for Research Validity
To ensure reliable data, consider the following:
- Within-Participant Changes: Ensure that each participant uses the same smartphone for all PVT sessions.
- Between-Participant Changes: Ensure that all participants use the same smartphone model to standardize response time measurements.

“Our partnership with NeuroUX began more than two years ago to develop the Healthy Actions and Lifestyles to Avoid Dementia (HALT-AD) Program, a digital platform aimed at reducing dementia risk via education and lifestyle modification support. NeuroUX’s expertise in software design and development has been a valuable asset to our team. Together, we have been using an iterative method of continuous cycles of product development and refinement to ensure HALT-AD is interactive, fun, and supportive for healthy midlife and older adults. It has been a very favorable collaborative relationship working with them.”

“The goal of our study is to test the efficacy of a dyadic sleep intervention program for persons living with dementia and their caregivers. NeuroUX made our research work so convenient for both staff and study participants. EMA sleep diary is so much easier than the paper version. It is very easy and quick to schedule the surveys. The interface is easy for study participants to navigate; they are able to quickly and easily answer the survey questions. The best feature is that the dashboard is super easy to read and quickly check the status of EMA surveys. It is also easy to download the data using other programs and identify missing data.”

“Typically, we conduct experiments in a laboratory and schools, but with the pandemic of COVID-19, this is no longer possible. NeuroUX has provided us with a powerful platform for reaching more of our participants at lower cost. They helped us transition our lab-based test to a mobile cognitive test which gathers useful data about how child cognition changes over time.”
